Our Canadian made, eco-friendly Bug Killer dust comes in a shaker bottle for easy dispensing. Bug Killer dust can be used to control insects on flowers and vegetables (including the Colorado potato beetle). It contains 2 food grade attractants which draws bugs to the powder. The powder contains silicon dioxide which kills by mechanical action both externally and internally when insects ingest it. The insects do not develop a resistance to this dust. It can be used 1 day before harvest.
